Yes, agree with Wild Mary. Your issue has less to do with the transformer model/type, and more to do with the fact that Williams locos run like jack rabbits with the dual motors. They're great trains but they do scoot.

There have been several threads here in the past about re-wiring them.

I have used all types of transformers with these engines and have had no problems. If the track is level, they will run reasonably slow, but not at a snails pace like Lionel & MTH with cruise control. Great engine, my scale GG1 pulls about 30 cars without a problem.

With my Williams F-7 set I had to add another powered unit to pull a full set of six passenger cars.

My two cents on rewiring, if I rewired the F-7's to run in series a snail would have gone faster than my Williams engines. Maybe my power company has a lower voltage rating or cycle frequency that I am not aware of, so to rewire a Williams for series just won't work for me.

This thing about rewiring a set of motors is something I have stayed away from, and with the brand new WBB you kill the warrenty instantly if you rewire the motors or anything else.

FYI, I have not used a CW-80 with any of my Williams engines. Maybe that transformer puts out a higher voltage or something when used with a Williams engine, so a rewire might be a consideration with that transformer?

I would try the diode method going to track power(inserting into the track between the transformer and lock-on power terminal first to see if you like that effect) rather than rewiring the motors in series, as you may not like the super slow effect.

One thing that happened by accident; I started a Williams GP-9 at wide open throttle with a ZW by mistake, and it sure took off, right off the track!! A few scratches on the side of my GP-9, but no real damage; nothing broke off and it still runs well today.

Was working on another engine and forgot to turn the power off before putting the plug back into the wall outlet.
